Open publisher page 0 citations

Abstract

Ephemeris error and clock error are the main source errors of GPS kinematics precise point positioning.Different ephemeris and clock difference will affect the results.This paper using the different ephemeris and clock difference from IGS website to calculate,using waypoint software to carry on different combination calculation with airborne GPS data,and analyzing the position and velocity results,have obtained some useful conclusion.
